It is the 17th most-seen of the 49 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January–February and September–October
In those months about 40% of wildlife watchers report a Gray Shrikethrush in Cradle Mountain-Lake St Clair National Park on a given day, against about 10% in March, the lowest month.

Across all the parks we cover, that three-hour window holds the most Gray Shrikethrush sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
12th of 19
Of the 19 parks where we can rate Gray Shrikethrush sightings, Cradle Mountain-Lake St Clair National Park ranks 12th at about 30%.

GBIF citizen-science records
It is estimated from how often the Gray Shrikethrush is recorded against all the birds logged in Cradle Mountain-Lake St Clair National Park (107 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
